Research on capacity allocation and economy of islanded microgrid

In this paper, the capacity allocation and economic loss of microgrid are studied. First, establish the time series model of islanded microgrid, considering the output characteristics of the energy storage system and wind turbine, using load shedding strategy and energy storage system control strategy, a reliability evaluation algorithm for micro grid operation is established. After that, considering different micro power supply capacity allocation, to evaluate the reliability of the improved IEEE-RBTS Bus 6 F4 feeder network. At last, the outage loss of microgrid under different capacity is calculated. The results show that, different configurations have great influence on the reliability and economy of microgrid.
